What If a needle or a grain of sand hits the earth at the speed of light?

Image
We are used to anticipating danger from outer space . A huge almost unknown space hostile to humans and no wonder colossal explosions take place asteroids and comets travel at tremendous speed . There are black holes and all this can potentially cause the death of the earth but what about something small for example an ordinary sewing needle what if one finds itself in space accelerates to the speed of light and then crashes into our planet .   Any object consisting of matter can't move at the speed of light or faster so scientists from NASA are unlikely to ever consider such a disaster well I will do it for them today you'll know how dangerous such small things can be if they are properly accelerated and at the same time, you'll learn about another strange scenario of the end of the world . Our planet is constantly bombarded by various cosmic bodies we don't even notice most of them they just burn up in the atmosphere .     Sometimes celestial b...

Does Aliens exist in our Galaxy...How can we connect with them ?

Image
Believe,  Yes, they do!  Here's why, As per the latest estimation, our Milky Way Galaxy contains between 200-400 Billion stars & there exist at least 100 billion potentially habitable Alien planets.

What is the estimated time our Earth will collapse ?

Image
In about 7.5 billion years our Sun will enter the  red giant phase  and expanded beyond Earth's current orbit. It will expand & consume the entire Earth. That's the most probable fate of Earth we know...

Are aliens real ?

Image
I think so aliens are real but there are 6 types of species found on our planet. One of them is animals and us but the other five are not yet known. We don't have that capability to see them. If you ever happen to read QURAN the Holy Book of Muslims, you could find that Allah has made Prophet (SAWW) Superior over all universes and all types of species. This hits a clue to our brains that aliens may be real. Our eye is blocked to see the other 5 types of species found on our own planet. I think so one of them includes ghosts also but who knows. We could only be able to find it after we are dead. - These are all my personal views only.

Some Facts About The Bermuda Triangle

Image
Bermuda Triangle also is known as  * Devil's Triangle * is one of the biggest mystery of science. Thousands of boats, ships & airplanes have been lost in this area & never found again. Here are some amazing facts about the  Bermuda Triangle, The Bermuda Triangle is not small. In fact, it is quite large and covers an area of 440,000 miles of the sea & its effect can be experienced outside of the triangle too. Whenever any plane or ship disappears in the Triangle, its debris cannot be found. The reason behind this is that Gulf Stream runs near the triangle, which quickly gets rid of the debris. At least 1000 lives are lost within the last 100 years. On average, 4 aircraft and 20 yachts go missing every year. People have experienced electronic fog in the Bermuda triangle, which can be a Time Travel Tunnel too. Pilot Bruce Gernon claims he lost 28 minutes after flying through a time-warping cloud tunnel. The plane went missing from radars, only to re-emerge in ...

What lies behind a Black Hole ?

Image
Black Holes sucks nearly everything that comes in their path, but where does that matter go? Some scientists believe that Black Holes ends up as a White Hole. Once you enter a Black Holes you will come out from the other end in some other universes or far somewhere far away. But it's just a theoretical idea, no scientific proofs.

Questions that science couldn't answer yet!! Can you ?

Here's a list of questions that science couldn't answer yet.  credit: TedEd Why do we dream? How did life begin? Are we alone in the universe? What makes us human? What is consciousness? Is the multiverse theory correct? What is dark matter & what are its properties? What is the purpose of human existence? How the Universe will end? How many species exist on earth? What lies beyond the Universe? How gravity works? What existed before the Big Bang? How does a bicycle stay upright? How & Why do we move forwards in time? Why does space have only three dimensions? Can we get energy from nothing? Is the universe really infinite or just very big? How does the brain generate consciousness? Can we replace damaged brain parts with computational devices? What happens when you die? What are the cures for the world's biggest health problems, like cancer and dementia? Can humans reverse or stop aging? Is there a limit to how smart humans can be? Is biology as universal as chemis...

Does God exists ?

Image
Well, religion has played a very important role in the ancient times. It united people in groups that stayed together & further transformed into today's modern world. The base of any religion is  God . We don't know if God is real because there are no scientific pieces of evidence of it. So, if there's a god we have nothing to worry about. We're good to go. But in order to prove something, science requires pieces of evidence that can be tested in a lab. God is a concept that can't be tested, also we have no evidence of it. So, it becomes our duty to make a change in our own existence & explore the unknown.

Machenism of Earth's Magnetic Field

Image
Fusion occurs at the center of our Sun, as a result of which it blasts the energetic particles ( Solar Winds ) like protons & electrons, all the time. Earth's Magnetic field prevents those energetic particles from reaching us. Just like that, w ithout magnetic field Oceans will evaporate, life will die because of radiation, greenery will vanish & finally, Earth will turn into Mars within a million years.

What if Earth stops rotating suddenly ?

Image
One day billions of years from now Earth will standstill, it will no longer be spinning because of the slowing down every moment. But chances are good that other events that will occur before that, such as the sun swallowing up the planet. With that being said, there isn’t a chance that the Earth will suddenly stop spinning anytime soon. But let’s just assume for a moment that the Earth did suddenly stop rotating, and take a look at what would happen to us, and the planet. Our planet spins at its equator 1000 miles per hour as it orbits the sun. But, as you get closer to the poles, the rotation is slower. Without this rotation, life as we know it wouldn’t be possible. It is said that billions of years ago, our planet used to spin much faster than it does now. At the beginning of our young solar system, an unknown planet or large celestial body collided with the Earth, and in that collision, the Earth's alignment and rotation were changed, and the moon was formed. Since then the E...

How many planets are there in our solar system ?

Image
Most of the people know that there are 8 planets in our solar system. Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune                           But, that's not true. According to scientists, there's a ninth planet in our solar system, I'm not talking about  Pluto. In 2014 astronomer observed something which wasn't fitting with the regular revolution of planets around the Sun. They were shocked to see that something was affecting the motion of planets around the sun. After years of research, they come up with a solution predicting that there's one more planet in our solar system. It was named as  Planet Nine. Calculations showed that planet nine has mass ten times of Earth & a diameter two to four times that of Earth. Planet Nine completes its an orbit around the sun in 10,000–20,000 years, it's semi-major axis is estimated to be 700 AU, which is roughly 20 times the distance from Neptune t...

How Mount Everest was formed ?

Image
The tallest mountain above sea level, Mount Everest, in the Himalaya Mountains. But millions of years ago, there were not the Himalayas. So, how was the  Mount Everest  formed? Let's go back in time & find out how Mount Everest was formed. About  60 million years ago  a huge collision between India and the Euro-Asian continent took place. The continental drift of the tectonic plates drove these two plates to the collision. Since both are continental plates, they clashed, crumpled, and formed the mountains of Himalayas, Mount Everest was one of them. Mount Everest is made of three layers of rocks, they are: 1. Limestone  - at the top 2. Marble  - at the middle 3. Himalayan granite  - at the bottom Here are some mind-blowing facts about Mount Everest. Everest is 29,035 feet, or 8848 meters high. The summit is the border of Nepal to the south and China or Tibet in the north. It is over 60 million years old. Everest grows by about a quarter of...

What are Comets ?

Image
A celestial object consisting a nucleus of ice and dust and when it goes near to the sun, a trail of dust and ice pointing away from the sun appears. You can say it a snowball of a solar system that produces a visible environment by outgassing. Actually, outgassing is a process used for producing gas.

What would happen if Apophis Astriod hits Earth's surface ?

Image
Apophis was discovered by  Roy A. Tucker ,  David J. Tholen  &  Fabrizio Bernardi  on June 19, 2004. It is a 400 meters wide & 26.99 billion kg heavy asteroid with an average orbital speed of 30.728 km/s. Astronomers calculated that there's a small possibility of Apophis hitting Earth in 2029 or 2036. So, what will happen if Apophis hits the Earth? On hitting Earth it will produce an Energy of more than  100 thousand Hiroshima bombs , which is enough to destroy an entire country. In case it lands in highly populated areas or countries like India, China, or America then it will kill millions of people within a few minutes of destruction. Now you might be wondering how do we stop this Asteroid from hitting Earth? Well, today we don't have any good practical solution to stop an asteroid that big. But, here are a few ideas that might be helpful in the future. Laser Beam -  By pointing a strong laser beam on the asteroid we can actually change...

What was the beginning of Universe?

Image
In the beginning, the Universe was nothing but a  Singularity.  A singularity is a point of infinite mass  & density. Singularity seems stable as we study it today, but in the early universe because of  quantum fluctuations , it wasn't stable at all. That instability resulted in a huge explosion we call  Big Bang. From our current understandings of Big Bang, Time or even Space didn't exist before the Big Bang, everything started altogether with this explosion. In the beginning, the Universe was like a very hot  soup  of pure energy having all the ingredients required for the formation of atoms. Within a few microseconds after Big Bang particles like quarks, leptons, gluons, Higgs, etc came into existence. But since the universe was expanding & cooling at a fast rate, these particles started to coalesce & formed other fundamental particles like electrons, protons & neutrons. But Universe was still expanding & cooling down, so the ...

Is it possible to travel in Time ?

Image
Yes, it is!  Scientists have been trying to find out new ways to travel in time for decades. Earlier it seems impossible, but not anymore. According to scientists,  Time Travel  is now just a  technical problem  that we need to solve. Here are a few possible ways to travel  forward in time , Orbiting a Black Hole -  As per Theory of Relativity we know, time slows down as we get closer to an object with high gravitational potential. Black Holes are the objects with intense gravitational potential, so if we could go closer to a Black Hole in a space-ship & orbit around it, then for us time will run slowly as compared to the people on Earth. But the problem with this idea is that Black Hole's gravity is so intense that it bends the space-time fabric & if our spaceship will try to approach a Black Hole it will probably never return. High Speed -  The faster you move, the slower the clock gets. Albert Einstein explained it as  Time ...

How the Universe and Solar System was formed ?

Image
Our universe was formed about 13.7 billion years ago after the  Big Bang  explosion. According to this theory, in the beginning, the universe was nothing but singularity. But the singularity exploded because of quantum fluctuations. As a result of this explosion vast amount of energy was released which later condensed & formed all the stuff that we observe today in the Universe. In the starting, our solar system was nothing but a cloud of dust. But with time gravity did it's magical work & formed sun at it's center. Soon after formation, all the other planets that we see begin.

What is the average temperature of Moon during night and how ?

Image
There is a molten zone within the moon but it is extremely small, which means it has a very small effect on its surface temperature. As a result in the lack of proper molten core & zero atmospheres the average temperature on the Moon surface varies from  -298 °F  (-183 °C) at night, to  224°F  (106 °C) during the day.

What will happen if Moon fell on Earth ?

Image
Moon is currently 384,400 km away from us. Its diameter is 3,474 km & the mass is 7.3 × 10^22 kg. So what will happen if Moon fell on Earth? Imagine moon just stopped orbiting & started moving towards Earth. On hitting earth it will release 10^20 Gigajoules of energy, which is 4 billion times the total energy of all nuclear weapons in the world right now. The impact will melt the Earth's crust where it hits & the average surface temperature will increase from 15˚C to 735˚C. As a result, Oceans & IceCaps will be vaporized within a few minutes & lava will cover the entire earth's surface. If the moon hits earth then probably our planet would never be able to sustain life again. But the fact is you don't need to worry about it because the moon is actually going away from earth at a rate of 3.8 centimeters per year. In about 50 billion years, the Moon will stop moving away from us and settle into a nice and stable orbit.

Why Venus is the hottest planet of Solar System when mercury is closer to Sun ?

Image
Yes, it's a common question that why  Venus  is the hottest planet when  Mercury  is closer to the Sun. Here's why, Our Sun is not just a source of continuous pure energy but also sometimes it produces streams of plasma or charged particles escaping from its upper atmosphere, we call them Solar Winds. Being the closest planet to the Sun, Mercury's atmosphere is being  blown away  by the solar winds since it's formation. Today, mercury has an almost negligible atmosphere, most of it contains particles from the solar wind other than traces of helium, hydrogen, and oxygen. So the side facing the Sun can be as hot as  427 degrees Celsius  and side facing away can be as cold as  -170 degrees Celsius . Whereas Venus has an atmosphere because it's is too far & the effect of winds is minimum. Having an atmosphere results in the heat of the sun  being trapped  inside Venus's atmosphere due to the phenomenon we call the  ...
